Photovoltaic energy is a free, clean and non pollutant renewable energy source. The costs of PV energy production have been reduced during the last decade and will continue decreasing in the future. On the other hand, prices for fossil energy sources increase dramatically. Therefore, photovoltaic energy is promising source of energy for many of world countries. The world trend nowadays is to find a non-depletable and clean source of energy. The most effective and harmless energy source is probably solar energy, which for many applications is so technically straightforward to use.Use of solar energy instead of fuel combustion, particularly for simple application like low and medium temperature water heating and for standalone PV systems in rural areas, can reduce the load on the environment. Solar energy for electricity generation can be harvested by the use of PV array, which has an optimum operating point called the maximum power point .
